Definitions

  • the present application relates to novel 2-aminoethoxyacetic acid derivatives, processes for their preparation and their use for the preparation of medicaments for the treatment and / or prophylaxis of diseases, in particular thromboembolic diseases.
  • Blood clotting is a protective mechanism of the organism, with the help of which defects in the vessel wall can be "sealed" quickly and reliably. Thus, a blood loss can be avoided or minimized.
  • Hemostasis following vascular injury is essentially through the coagulation system, which triggers an enzymatic cascade of complex plasma protein reactions.
  • At the end of the cascade is the conversion of the soluble fibrinogen into the insoluble fibrin, resulting in a blood clot.
  • blood clotting distinguishes between the intrinsic and extrinsic systems, which result in a final common pathway.
  • factor Xa which is formed by the proenzyme factor X, plays a key role, since it combines both coagulation pathways.
  • the activated serine protease Xa cleaves prothrombin to thrombin.
  • the resulting thrombin in turn splits fibrinogen to fibrin.
  • Subsequent cross-linking of the fibrin monomers leads to the formation of blood clots and thus to haemostasis.
  • thrombin is a potent trigger of platelet aggregation, which also makes a significant contribution to hemostasis.
  • Hemostasis is subject to a complex regulatory mechanism.
  • An uncontrolled activation of the coagulation system or a defective inhibition of the activation processes can cause the formation of local thromboses or embolisms in vessels (arteries, veins, lymphatics) or cardiac cavities. This can lead to serious thromboembolic diseases.
  • hypercoagulability - systemically - in a consumption coagulopathy can lead to disseminated intravascular coagulation.
  • Thromboembolic complications also occur in microangiopathic hemolytic anemias, extracorporeal blood circuits such as hemodialysis, and heart valve prostheses.
  • Thromboembolic disease is the leading cause of mortality and mortality in most industrialized countries [ Heart Disease: A Textbook of Cardiovascular Medicine, Eugene Braunwald, 5th Ed., 1997, WB Saunders Company, Philadelphia ].
  • heparin is used, which is administered parenterally or subcutaneously. Due to more favorable pharmacokinetic properties, although increasingly low molecular weight heparin is nowadays increasingly preferred; However, this also the known disadvantages described below can not be avoided, which consist in the therapy with heparin. Thus, heparin is orally ineffective and has only a comparatively low half-life. Since heparin simultaneously inhibits several factors of the blood coagulation cascade, there is an unselective effect.
  • a second class of anticoagulants are the vitamin K antagonists. These include, for example, 1,3-indandiones, but especially compounds such as warfarin, phenprocoumon, dicumarol and other coumarin derivatives, which are unsuitable for the synthesis of various products of certain vitamin K-dependent coagulation factors in the liver. Due to the mechanism of action, the effect is only very slow (latency until the onset 36 to 48 hours). Although the compounds can be administered orally, due to the high risk of bleeding and the narrow therapeutic index, a complex individual adjustment and observation of the patient is necessary [ J. Hirsh, J.
  • factor Xa is one of the most important targets for anticoagulant drugs [ J. Hauptmann, J. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S. S.
